Traditional magnifying glasses can give magnified virtual images with diffraction‐limited resolution, that is, detailed information is lost. Here, a novel magnifying glass by transformation optics, referred to as a “superresolution magnifying glass” (SMG) is designed, which can produce magnified virtual images with a predetermined magnification factor and resolve subwavelength details (i.e., light sources with subwavelength distances can be resolved). Based on theoretical calculations and reductions, a metallic plate structure to produce the reduced SMG in microwave frequencies, which gives good performance verified by both numerical simulations and experimental results, is proposed and realized. The function of SMG is to create a superresolution virtual image, unlike traditional superresolution imaging devices that create real images. The proposed SMG will create a new branch of superresolution imaging technology.

用于通过转换光学对亚波长分辨率进行虚拟成像的放大镜

传统的放大镜可以提供衍射极限分辨率的放大的虚拟图像，即丢失了详细的信息。在这里，设计了一种新型的通过转换光学器件的放大镜，称为“超分辨率放大镜”（SMG），它可以产生具有预定放大倍数的放大虚像并解析子波长细节（即，具有子波长距离的光源可以解决）。基于理论计算和归约法，提出并实现了一种金属板结构，该结构能在微波频率下产生降低的SMG，并通过数值模拟和实验结果验证了良好的性能。与创建真实图像的传统超分辨率成像设备不同，SMG的功能是创建超分辨率虚拟图像。
